Iran has opposed the U.S. presence and policies in Iraq and the United States has accused Iran of backing militants in Iraq.

Jannati said the U.S. was trapped in a quagmire in Iraq and didn't know what to do about it.

"The shoe hurling by the Iraqi journalist had many messages which the world received and the Iraqi people, too, held demonstrations afterwards. People should support the Iraqi journalist," said Jannati, who believes shoes should be regular props in the anti-U.S. demonstrations in Iran and Iraq.
